TYPEWRIrINe I' MACHINE.

Application led June 9, 1922. Serial No. 566,983.

The present invention relates to casings and mountings for portabletypewriting machines.

Heretofore, the casing in which a. portable typewriting machine has beencarried has been constructed in two parts; to wit, a basepiece to whichthe machine is attachable, and which may serve as a base-board in theoperation of the machine, and a cover which may be set down over thebase-piece and over the machine attached thereto. Suitable means forsecuring the base-piece to the cover, for transporting the machine, anda handle on the cover have also been provided. As casings haveheretofore been construct ed and held together, with the machine en`closed therein, theweight of the machine, in the transportation thereof,has fallen upon walls of the casing other than the wall having thehandle by which the casing is carried.

An object of the present invention is the provision of means whereby, inthe transportation of the machine by a handle on the casing, the weightof the .machine may be caused fto fall on the casing wall which has thehandle, and preferably to fall immediately under the handle; so that thecasing may be made of extremely light material without chance ofdistortion or springing of its joints and locks under the weight of themachine.

A feature of the invention is the provision of means whereby the machinemay be engaged and directly supported by the cover (suspended from onewall ofthe latter), instead of, as heretofore, being supportedindirectly by the cover through the intermediary of the base-piece towhich the machine is attached.

A feature of the invention is its adaptay bility to a centering of theweight of the machine with respect to the casing, thereby avoidingbending and twisting strains on the casing and handle, and making thecasing more durable and more convenient to carry.

A further feature of the invention is the provision of means forsupporting the machine from the casing cover, which supporting meanscomes automatically to effective Referring to the drawings, the casingis shown as comprising a base-piece 10 and a i cover 11. For holding thebasepiece to the cover, the latter, at its rear near each end thereof,has riveted to its inner wall apair of guards 12 offset at 13 to overlapand hold the base-piece when the latter is in place. The base-piece withthe machinev thereon is inserted in the cover in tilted position tobring the rear edge of the' base-piece over the osets 13 of the upon thebase-piece is swung into the cover in the Figure 1 position. In eachcorner of the cover is an elongated block 14, the lower ends 15 of whichserve Vas stops for a peripheral flange 16 formed on the base-piece. Atits forward end, the base-piece is held to the cover by a bolt 17on alinger-piece 18 hinged'to a plate 19 on the outer face of the cover. Theplate 19 is riveted through the cover to a plate 20 on the inner facethereof. lThe bolt 17 passes through an aperture 21 inthe cover` andinto a recess 22 in the basepiece, in which position it may be locked bya key, not shown. l i

The base-piece is provided with front and rear rubber feet 23, to serveas a sounddeadening support for the base-piece with the machine'thereonwhenV the latter is in use. handle consisting of a strap 24. held byguards 12; and there- .Y

The casing is also provided with a Y bands 25 on a plate 26, which issecured and an outer or ornamental frame 29 se-V cured to the innerframe by screws 30. The

platen 31 is shown as mounted in a frame 32 supported by roller bearings33 and `34 i to have movement in letter-feed and return directions on ashift-frame 35 pivoted at 36 to the main frame 28. Type-keys areindicated at 37; a line-space lever at 38; and a carriage-returnfinger-piece at 39. The machine shown in the drawings is an Underwoodstandard portable typewriter.

An finwardly-turned lip or fiange 40'is formed on each side of theframe' 28. rllhe machine is supported by these vflanges on four blocks4l, towit, two at the front and two atthe rear, of'compressed orhardened felt. For securing the machineto'th'e basepiece, screws 49.pass through the flanges 40 and thread into nuts set into the bottom ofthe base-piece. 'lhevynuts 43 are squared so as to'be held againstrotation' when the screws 42 are tightened, and 4are shoiildered at 44to holdtliesame against movement through Vthe base-piece against thepull of the. screws when thelatter are tightened.y p `Gruardsf45 securedby screws, 46 to the vtop Vofthe base-piece have offsets 47,

which, when the guards yare set in place,

overlap the front ends of the flanges 40 and Vassist in r.holding themfixedly to the base-piece. Guards 4S secured by screws 49 to thebase-piece at. the rear thereof have offsets 5'() adapted to be at setinto holes in llugs 51 formed on the Iframe QS near the rear of thelatter; and, when these guards are in place, theyI assist the screws 42and the guards 45 in holding the niachine against movement on thebase-piece.

The lshiftable parts ofthe machine are held against movement inthecasing by blocks of felt. ,A felt bloclr53 positioned centrally of thecasing ycover servesas an abutment for the top of tlie'plateii, and thusholds the shiftlframe, andparts carried' thereby, in place when vthemachine is "in the casing. The felt blocks v'41and 53 are gluedorVotherwise suitably secured to the v'casing members. v

A purpose of the Vpresent invention being to 'support they 'base-pieceandthe attached machine from the end walli54v'of the casing cover, thelatter has secnre'd by screws 55, to the inner'faefthereof, a pair ofvhooks 56. Thesehooks {arer spaced well apart, so'that'the noses57vthereof may engage a flange 5Son `the front plate 59 of the outsideframe 29 beyond the ends of theA space-bar 62,:see Figure 2. As yshown'in the drawings, the noses 57'- o'f :the hooks are ofset'laterally'toprovide `considerable bearing for the machine frame; and are offset at60 rearward with respect tor theV ma-` chine, so that, in swinging-fthebase-piece of the machine 'into the casingv cover, the flange 58 on theouter machineframe will viindthe hooks and be cammed by the latter intoproper position .0n the hooks, as Vshown in Figure l. llhen the frontplate of the machine is in Figure l engagement with the hooks, thecasing cover, eXcept for the end wall 54 thereof, is relieved of theweight of the base-piece and attached machine.

It will be noted that the joints between the cover and the base-piece atthe front and rearare sufficiently loosef-to'permit the base-piece andattached m-acliiue'tobe carriedbyV the hooks 56 free of the end wallGlfo'f'the casingcover. .f

Variationsmay be resortedfto within the scope of the invention, andportions of the -in'iprovem-ents may be used without others.
